This modulation provides for high noise margins and excellent immunity against isolation-mode transients. The modulator data and on-chip sampling clock are encoded and transmitted across the isolation boundary where they are recovered and decoded into separate high-speed clock and data channels.

The need for optical isolation technology is ever increasing in power electronics circuits. Avago Technologies offers a vast choice of high performance digital and analog optocouplers as well as application-specific devices that contain isolation amplifier and power transistor driver functions especially suited for isolating signals in various motor control and power electronics circuits. In addition to optocouplers, Avago Technologies offers fiber-optic transmitters and receivers, and motion sensing components for industrial applications.

Description and Extent of Change: Avago Technologies will change the barcode label to provide for the name of country of origin in full. In doing so, the following changes will be made: (1) The naming convention for country of origin to made in (2) 2-alpha country code in both text and barcode to name of origin country of the product shipped in full (3) To provide for the required space for the country of origin, the dept ID will move moved up to the same line as vendor ID. Please see below diagram on the changes made.

Optocouplers are used extensively for high-voltage isolation and electrical noise rejection – two essential requirements for transmitting correct information between different voltage potentials within an electrical system. Such systems must be able to operate reliably for many years when used in industrial, medical, renewable energy environments, and any other system that has a long expected operating lifetime.

The introduction of electric and hybrid electric vehicles have added high voltage electric modules into the car. The battery stack in a hybrid can be in excess of 150V, higher for the inverter driving the motor.

Industrial communication includes data monitoring and processing, diagnostic and sensing as well as visualization. To maintain data integrity against group loop current or common mode noise, optocouplers are used to eliminate both problems.
